If the nipple examong other objects, aims to provide improved tended only half-way into the mixing tank, the apparatus of the stated character which will steam blast from the discharge end of the pipe thoroughly cleanse all the surfaces of a standard I! mightcut off almost all the flow through the milk can with a sprayed solution whose temperanipple, thus spraying an excessive proportion of ture, force and cleansing or sterilizing strength the solution on the outside of the can. The armay be accurately controlled. The invention rangement shown insures a p p distribution also provides apparatus which permits substanof the solution both inside and outside. tially all the sprayed solution to be recovered At the end of the mixing tank pp to p p and used again.
